FIELD: contact welding of materials. SUBSTANCE: method of contact welding of material comprises steps of placing a gasket of an active material between members to be welded before compressing them, the above mentioned active material having conversion heat, equal to 500-1300 kcal/kg, a thickness of the gasket, equal to (0.2-2.0) of a thickness of the members to be welded; passing a pulse of an electric current through the members and the gasket, having a current intensity up to 32 kA, a duration of the pulse, equal to (1010-3 - 3), s with pressure, acting on the members, equal to (2-100)kgf/cmkgf/cm2. EFFECT: possibility of high strength welding of different-type and hard-to-weld materials, composite materials. 1 cl
